Detailed Embodiments

[0019] The present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0020] Reference Figure 1 , an embodiment of the present application discloses a charging control method for a charging pile, including the following steps: Step 100: Obtain the charging signal of the preset charging pile.

[0021] A charging pile refers to a device that provides charging services for electric vehicles. A charging signal refers to a signal sent when the charging pile needs to be used. The charging signal is obtained through a signal transceiver on the charging pile.

[0022] Step 101: Determine the charging mode according to the charging signal.

[0023] The charging mode refers to a combination of different methods and strategies adopted when charging a vehicle. The charging mode corresponding to the charging signal can be matched through a preset mode database, which stores different charging modes corresponding to different charging signals. The mode database is pre-input by those skilled in the art and will not be elaborated here.

[0024] Step 102: When the charging mode is not the preset Bluetooth mode, obtain the card swiping number information of the charging pile.

[0025] The Bluetooth mode refers to a mode that realizes communication and connection between a vehicle and a charging pile through Bluetooth technology and starts the charging process by pairing the mobile phone Bluetooth with the charging pile. The card swiping number information refers to the unique identification coding information of the card read by the charging pile when a charging card is operated on the charging pile. The card swiping number information is obtained through a preset card reader on the charging pile after the operator swipes the card. The Bluetooth mode is set by those skilled in the art in advance and will not be elaborated here.

[0026] When the charging mode is not the Bluetooth mode, it means that the operator needs to use card swiping for charging, and the card swiping number information of the charging pile needs to be obtained for subsequent steps.

[0027] Step 103: When the card swiping number information is inconsistent with the preset reference number information, report a number anomaly prompt and determine the reference charging position according to the card swiping number information.

[0028] The reference number information refers to the identification coding information corresponding to the charging pile. Each charging pile is correspondingly set with the corresponding card swiping number information at the time of leaving the factory. The reference number information is set by those skilled in the art in advance and will not be elaborated here. The reference charging position refers to the position of the charging pile corresponding to the card swiping number information. The reference charging position corresponding to the card swiping number information can be matched through a preset charging pile database, which stores the reference charging positions corresponding to different card swiping number information. The charging pile database is formed by those skilled in the art recording the reference charging positions corresponding to different card swiping number information in sequence and will not be elaborated here.

[0029] When the swiped card number information is inconsistent with the reference number information, it indicates that the operator has selected the wrong charging pile. An abnormal number prompt needs to be reported, and then the reference charging position is matched for subsequent steps.

[0030] Step 104: Control the current charging pile to report a prompt based on the reference charging position.

[0031] Control the current charging pile to report the reference charging position as a prompt, so as to prompt the operator to go to the correct charging pile for charging.

[0032] Step 105: When the swiped card number information is consistent with the preset reference number information, control the charging pile to charge the vehicle with a preset charging method.

[0033] The charging method refers to the method by which the charging pile charges the vehicle. The specific charging method will be described in detail in subsequent Steps 500 to 604 and will not be elaborated here.

[0034] When the swiped card number information is consistent with the reference number information, it indicates that the operator has not selected the wrong charging pile. Just directly control the charging pile to charge the vehicle with the charging method.

[0035] Refer to Figure 2 , and further includes the following steps: Step 200: When the charging mode is the preset Bluetooth mode, obtain the charging image information of the charging pile.

[0036] The charging image information refers to an image in front of the charging pile that includes the vehicle to be charged. The charging image information is obtained by taking a photo with a preset camera on the charging pile.

[0037] When the charging mode is the Bluetooth mode, it is necessary to obtain the charging image information of the charging pile for subsequent steps.

[0038] Step 201: Determine the vehicle model information based on the charging image information and the preset vehicle characteristics.

[0039] The vehicle characteristics refer to the characteristics of the appearance and contour of the vehicle. The vehicle characteristics are set in advance by those skilled in the art and will not be elaborated here. The vehicle model information refers to a set of specific codes used to accurately identify the specific type, model, and configuration of the vehicle. By performing feature recognition on the vehicle from the charging image information, the characteristics of the vehicle to be charged are obtained, and then the vehicle model information corresponding to the vehicle characteristics is matched from the preset model database. The model database stores different vehicle model information corresponding to various vehicle characteristics. The model database is formed by those skilled in the art sequentially recording the different vehicle model information corresponding to different vehicle characteristics and will not be elaborated here.

[0040] Step 202: Determine the charging port location based on the vehicle signal information.

[0041] The charging port location refers to the location of the charging port of the vehicle to be charged. The charging port location corresponding to the vehicle signal information can be matched through a preset charging port database, which stores different charging port locations corresponding to different vehicle signal information. The charging port database is formed by those skilled in the art recording the different charging port locations corresponding to different vehicle signal information one by one, which will not be elaborated here.

[0042] Step 203: Determine the charging gun movement route based on the charging image information, the charging port location, and the preset charging pile location.

[0043] The charging pile location refers to the installation location of the charging pile. The charging pile location is set in advance by those skilled in the art, which will not be elaborated here. The charging gun movement route refers to the movement route required before the charging gun on the charging pile is docked with the charging port. By analyzing the charging image information, the positions, shapes, and sizes of various objects and obstacles in the image are identified, and then the charging port location and the charging pile location are used as the starting point (charging pile location) and the ending point (charging port location) of the route. Finally, a path planning algorithm is used to obtain the charging gun movement route. The path planning algorithm is common knowledge in the art, which will not be elaborated here. The charging gun refers to an object used to dock with the charging port of the vehicle to charge the vehicle.

[0044] Step 204: Based on the charging gun movement route, control the preset charging mobile device to move the preset charging gun to the charging port location to complete the charging docking.

[0045] The charging mobile device refers to a device used to control the movement of the charging gun. Control the charging mobile device to move the charging gun to the charging port location according to the charging gun movement route to complete the charging docking.

[0046] Step 205: After completing the charging docking, control the charging pile to charge according to the preset charging method.

[0047] After completing the charging docking, control the charging pile to charge the vehicle according to the charging method.

[0048] Refer to Figure 3 , and it also includes steps before obtaining the charging signal of the preset charging pile: Step 300: Obtain the pre-pile image information of the preset charging pile.

[0049] The pre-pile image information refers to the image presented in front of the charging pile. The pre-pile image information is obtained by taking pictures with the camera on the charging pile.

[0050] Step 301: When the pre-pile image information contains preset vehicle features, determine the license plate color based on the pre-pile image information and the preset license plate features.

[0051] The license plate features refer to the appearance, contour, and color features of the license plate. The license plate features are preset by those skilled in the art and will not be elaborated here. The license plate color refers to the color of the license plate. By performing color recognition on the license plate features in the pre-pile image information, the license plate color can be obtained. Image recognition technology is common knowledge in the art and will not be elaborated here.

[0052] When the pre-pile image information contains vehicle features, it indicates that a vehicle is parked in front of the charging pile. It is necessary to first determine the license plate color for subsequent steps.

[0053] Step 302: Determine the vehicle attribute based on the license plate color.

[0054] The vehicle attribute refers to the information used to reflect the energy type of the vehicle itself. Through a preset attribute database, the vehicle attribute corresponding to the license plate color can be matched. Different vehicle attributes corresponding to different license plate colors are stored in this database. The attribute database is formed by those skilled in the art recording different vehicle attributes corresponding to different license plate colors in sequence and will not be elaborated here.

[0055] Step 303: When the vehicle attribute is a preset fuel-powered vehicle, report a vehicle occupancy prompt.

[0056] A fuel-powered vehicle refers to a vehicle with a fuel engine as the main power source. When the vehicle attribute is a fuel-powered vehicle, it indicates that the vehicle cannot be charged and a vehicle occupancy prompt needs to be reported.

[0057] Step 304: When the vehicle attribute is a preset electric-powered vehicle, obtain the charging demand signal of the charging pile.

[0058] An electric-powered vehicle refers to a vehicle mainly relying on electric energy as the power source. The charging demand signal refers to the signal used to know whether the vehicle needs to be charged. The charging demand signal includes a need-to-charge signal and a no-need-to-charge signal. The need-to-charge signal refers to the signal that the vehicle needs to be charged. The no-need-to-charge signal refers to the signal that the vehicle does not need to be charged. The need-to-charge signal and the no-need-to-charge signal are both preset by those skilled in the art and will not be elaborated here. The charging demand signal is obtained through the signal transceiver on the charging pile. When the vehicle needs to be charged, the signal transceiver on the charging pile will send out a need-to-charge signal. When the vehicle does not need to be charged, the signal transceiver on the charging pile will continuously send out a no-need-to-charge signal until the vehicle needs to be charged.

[0059] When the vehicle attribute is an electric-powered vehicle, it is necessary to obtain the charging demand signal of the charging pile for subsequent steps.

[0060] Step 305: When the charging demand signal is consistent with the preset need - to - charge signal, determine the current vehicle attitude based on the image information in front of the charging pile and vehicle characteristics.

[0061] The current vehicle attitude refers to the actual placement state of the vehicle in front of the charging pile. By identifying the vehicle characteristics in the image information in front of the pile, the current vehicle attitude can be obtained. Image recognition technology is well - known common knowledge in this field and will not be elaborated here.

[0062] When the charging demand signal is consistent with the need - to - charge signal, it indicates that the vehicle needs to be charged. First, the current vehicle attitude needs to be determined for subsequent steps.

[0063] Step 306: When the current vehicle attitude is inconsistent with the preset reference vehicle attitude, control the charging pile to adjust the vehicle attitude by a preset attitude adjustment method, and after completing the attitude adjustment, obtain the charging signal of the charging pile.

[0064] The reference vehicle attitude refers to the placement state that the vehicle should be in front of the charging pile if it needs to be charged. The reference vehicle attitude is set in advance by those skilled in the art and will not be elaborated here. The attitude adjustment method refers to the method used to adjust the attitude of the vehicle. The specific attitude adjustment method will be described in detail in subsequent steps 400 to 404 and will not be elaborated here.

[0065] When the current vehicle attitude is inconsistent with the reference vehicle attitude, it indicates that the placement state of the vehicle is incorrect. It is necessary to control the charging pile to adjust the vehicle attitude by the attitude adjustment method, and after completing the attitude adjustment, obtain the charging signal of the charging pile to proceed with subsequent steps.

[0066] Refer to Figure 4 , the attitude adjustment method includes the following steps: Step 400: Determine the vehicle model information based on the image information in front of the charging pile and vehicle characteristics.

[0067] This step is the same as step 201 above and will not be elaborated here.

[0068] Step 401: Based on a preset parking database, determine whether the vehicle corresponding to the vehicle model information includes a preset parking function.

[0069] The parking function refers to the function that a vehicle possesses to automatically park the vehicle in a designated parking space. The parking function is set in advance by those skilled in the art and will not be elaborated here. By determining whether the vehicle corresponding to the vehicle model information includes the parking function, it can be known whether the vehicle can be controlled to automatically adjust its posture. The parking database stores various functions corresponding to various vehicle model information, and various functions include the parking function. It can be judged whether the vehicle corresponding to the vehicle model information includes the parking function in the parking database. The parking database is formed by those skilled in the art successively recording various functions corresponding to various vehicle model information and will not be elaborated here.

[0070] Step 402: When the vehicle corresponding to the vehicle model information does not include the parking function, report a vehicle posture adjustment prompt.

[0071] When the vehicle corresponding to the vehicle model information does not include the parking function, it means that the vehicle cannot be controlled to automatically adjust its posture, and a vehicle posture adjustment prompt needs to be reported to prompt the operator to adjust the posture of the vehicle.

[0072] Step 403: When the vehicle corresponding to the vehicle model information includes the parking function, obtain the parking permission.

[0073] The parking permission refers to the permission that allows the charging pile to control the vehicle to use the parking function. When the vehicle corresponding to the vehicle model information includes the parking function, the charging pile will send a notification for obtaining the parking permission to the operator's mobile phone device or in-vehicle device. After the operator agrees, the parking permission can be obtained. If the operator does not agree, a vehicle posture adjustment prompt will be reported.

[0074] When the vehicle corresponding to the vehicle model information includes the parking function, it means that the vehicle can be controlled to automatically adjust its posture, and the parking permission of the vehicle needs to be obtained for subsequent steps.

[0075] Step 404: Based on the parking permission, control the charging pile to establish a signal connection with the vehicle corresponding to the vehicle model information, and after the connection is completed, control the vehicle to perform automatic parking.

[0076] After the operator grants the parking permission, the charging pile can be controlled to establish a signal connection with the vehicle corresponding to the vehicle model information. After the connection is completed, the vehicle is controlled to perform automatic parking to complete the adjustment of the vehicle posture.

[0077] Refer to Figure 5 , the charging method includes the following steps: Step 500: Determine the license plate number according to the charging image information and the preset license plate features.

[0078] The license plate number refers to the license plate of a vehicle. The license plate number can be identified by performing character recognition on the license plate features in the charging image information. Image recognition technology is common knowledge in this field and will not be elaborated here.

[0079] Step 501: Determine whether the preset charging database contains historical charging data of the vehicle corresponding to the license plate number.

[0080] Historical charging data refers to the relevant record information of the vehicle's charging in the past period of time. In this embodiment, the specific time is the previous 30 days. By judging whether the charging database contains the historical charging data of the vehicle corresponding to the license plate number, it can be known whether the vehicle has performed a charging operation on the current type of charging pile before. When the vehicle has performed a charging operation on the current type of charging pile, the charging database will store the charging data of the current vehicle according to the license plate number. These charging data will be saved for 30 days as historical charging data for subsequent queries. The charging database is a manually set database and will not be elaborated here.

[0081] Step 502: If it contains, determine the charging habit according to the historical charging data.

[0082] Charging habit refers to the behavioral patterns and preferences that show certain regularity and repeatability during the long-term charging process of a vehicle. Through the preset habit database, the charging habit corresponding to the historical charging data can be matched. This database will analyze the historical charging data to obtain the charging habit corresponding to the historical charging data. For example, analyze the start time of each charging of the vehicle in the past 30 days from the time dimension, and count the most frequently occurring charging periods. From the power dimension, calculate the power difference before and after each charging to understand the usual charging amount range of the vehicle. From the location dimension, count the number of charging times of the vehicle at different charging pile positions to clarify the area where it often charges. In this way, the charging habit corresponding to the historical charging data is obtained. The habit database is a manually set database and will not be elaborated here.

[0083] If the charging database contains the historical charging data of the vehicle corresponding to the license plate number, it means that the vehicle has performed a charging operation on the current type of charging pile. It is necessary to first determine the charging habit for subsequent steps.

[0084] Step 503: Obtain the current charging time.

[0085] The current charging time refers to the current time point. The current charging time is obtained through the time sensor preset on the charging pile.

[0086] Step 504: Determine the charging demand power according to the current charging time and the charging habit.

[0087] The charging demand power refers to the power value that the charging pile needs to output to achieve an ideal charging effect based on the vehicle's charging habits and the actual demand at the current time point when the vehicle is charging. Through a preset power database, the charging demand power corresponding to the current charging time and charging habits can be matched. Different charging demand powers corresponding to different current charging times and charging habits are stored in this database. The power database is formed by technicians in the field recording different charging demand powers corresponding to different current charging times and charging habits in sequence, which will not be elaborated here.

[0088] For example, when the vehicle's charging habit shows that it often charges from 7 pm to 10 pm on weekdays, and each time it charges from 30% to 80% of the battery level. Suppose the current charging time is 7:15 pm on a weekday and the vehicle's battery level is 32%.

[0089] In the power database, technicians have previously recorded a large amount of data on the charging demand power corresponding to such charging habits and different current time points. For the situation of starting to charge from the 30% battery level around 7 pm on weekdays, the database shows that if it is expected to charge the battery from 32% to 80% within a regular 2.5 hours, based on a vehicle battery capacity of 50 kWh, the additional power required is (80% - 32%) × 50 = 24 kWh, and the corresponding charging demand power is 24 kWh ÷ 2.5 h = 9.6 kW.

[0090] Step 505: Determine the urgent charging situation according to the charging demand power.

[0091] The urgent charging situation refers to the situation for knowing whether the vehicle urgently needs to charge at present. Through a preset urgent database, the urgent charging situation corresponding to the charging demand power can be matched. Different urgent charging situations corresponding to different charging demand powers are stored in this database. The urgent database is formed by technicians in the field recording different urgent charging situations corresponding to different charging demand powers in sequence, which will not be elaborated here.

[0092] Step 506: When the urgent charging situation is consistent with the preset urgent charging situation, control the charging pile to charge at the charging demand power.

[0093] The urgent charging situation means that the vehicle urgently needs to charge at present. The urgent charging situation is set in advance by technicians in the field, which will not be elaborated here.

[0094] When the urgent charging situation is consistent with the urgent charging situation, it means that the vehicle urgently needs to charge at present, and then directly control the charging pile to charge at the charging demand power.

[0095] Step 507: If not included, obtain the charging demand power.

[0096] The charging demand power is obtained after the operator clicks the charging power selection button on the charging pile. Multiple charging power selection buttons are set on the charging pile. Each charging power selection button corresponds to a different charging demand power.

[0097] If the historical charging data of the vehicle corresponding to the license plate number is not included in the charging database, it means that the vehicle has not performed a charging operation on the current model of the charging pile. Then, the charging demand power can be directly obtained and used for the subsequent steps 505 to 506.

[0098] Refer to Figure 6 , the charging method further includes the following steps: Step 600: When the charging urgency situation is inconsistent with the preset urgent charging situation, obtain the remaining vehicle power, the peak-valley electricity price of the power grid, and the vehicle usage time.

[0099] The remaining vehicle power refers to the remaining power of the vehicle. The peak-valley electricity price of the power grid means that the power department divides a period such as a day or a week into different periods such as peak and valley according to the change of the power grid load, and formulates differentiated electricity prices for different periods. The vehicle usage time refers to the specific time point when the operator plans to use the vehicle to carry out a journey. The remaining vehicle power is obtained by reading the power display system of the vehicle itself. The peak-valley electricity price of the power grid is pre-input by those skilled in the art. The vehicle usage time is pre-input by the operator.

[0100] When the charging urgency situation is inconsistent with the urgent charging situation, it means that the vehicle does not need urgent charging. It is necessary to obtain the remaining vehicle power, the peak-valley electricity price of the power grid, and the vehicle usage time for subsequent steps.

[0101] Step 601: Determine the vehicle charging period according to the current charging time and the vehicle usage time.

[0102] The vehicle charging period refers to the specific time period when the vehicle is charged. The vehicle charging period can be obtained by calculating the time difference between the current charging time and the vehicle usage time.

[0103] Step 602: Determine the required charging power according to the remaining vehicle power and the preset fully charged vehicle power.

[0104] The fully charged vehicle power refers to the power of the vehicle after the battery is fully charged. The fully charged vehicle power is set in advance by those skilled in the art and will not be elaborated here. The required charging power refers to the power that the vehicle needs to be charged. The required charging power can be obtained by calculating the difference between the fully charged vehicle power and the remaining vehicle power.

[0105] Step 603: Determine the charging power change parameter according to the required charging power, the vehicle charging period, and the peak-valley electricity price of the power grid.

[0106] The charging power change parameter refers to the change value of the charging power during the vehicle charging process when adjusted at different charging time points. Through a preset change database, the charging power change parameters corresponding to the required charging power, the vehicle charging period, and the peak-valley electricity price of the power grid can be matched. Different charging power change parameters corresponding to different required charging powers, vehicle charging periods, and peak-valley electricity prices of the power grid are stored in this database. The change database is formed by the technicians in this field recording the different charging power change parameters corresponding to different required charging powers, vehicle charging periods, and peak-valley electricity prices of the power grid after successive tests, which will not be elaborated here.

[0107] Taking an example, assume that an electric vehicle needs to charge 30 kWh, and the vehicle charging period is from 10 p.m. to 6 a.m. the next day (this is the low electricity price period of the power grid). In the change database, the technicians have recorded through multiple tests before. For the situation where the required charging power is in the range of 25 - 35 kWh and charging during the low electricity price period from 10 p.m. to 6 a.m. the next day, the corresponding charging power change parameters are: the power is set to 15 kW in the first 2 hours, and then as the battery charge gradually increases, to protect the battery performance, the power decreases by 1 kW per hour until the battery is fully charged.

[0108] Another example, for another vehicle that needs to charge 15 kWh, and the vehicle charging period is from 4 p.m. to 6 p.m. on weekdays (which belongs to the peak electricity price period of the power grid). The change database shows that for such a scenario where the required charging power is in the range of 10 - 20 kWh and charging during the peak electricity price period, the charging power change parameters are set as: keep charging at a relatively low power of 5 kW throughout the process to reduce the use cost of high-price electricity and avoid causing a large load impact on the peak period of the power grid at the same time.

[0109] Step 604: Control the charging pile to charge the vehicle based on the charging power change parameter.

[0110] Control the charging pile to charge the vehicle with the charging power change parameter.

[0111] Refer to Figure 7 , and further includes the following steps: Step 700: Based on when the vehicle is charging, obtain the received power value of the vehicle.

[0112] The received power value refers to the magnitude of the electric power actually received by the vehicle from the charging gun during the charging process. The received power value is obtained through the vehicle battery management system of the vehicle. When the charging gun is docked with the vehicle, the vehicle battery management system of the vehicle will communicate with the charging pile, and thus the charging pile can obtain the received power value in the vehicle battery management system.

[0113] When the vehicle is charging, it is necessary to obtain the received power value of the vehicle for subsequent steps.

[0114] Step 701: Determine the reference power value according to the charging power change parameter and the current charging time.

[0115] The reference power value refers to the power value output by the charging pile at the current charging time. By knowing the current charging time and combining the charging power change parameter, the specific power value to which the charging power changes at the current time point can be known, and thus the reference power value can be obtained.

[0116] Step 702: When the output power value is inconsistent with the reference power value, obtain the charging abnormal signal of the charging gun.

[0117] The charging abnormal signal refers to the signal sent by the system to indicate an abnormal charging situation during charging when the output power value of the charging pile is inconsistent with the reference power value. The charging abnormal signal is obtained through the signal transceiver on the charging gun.

[0118] When the output power value is inconsistent with the reference power value, it indicates that there is an abnormality in the cable on the charging gun. It is necessary to first obtain the charging abnormal signal of the charging gun for subsequent steps.

[0119] Step 703: Determine the abnormal cable according to the charging abnormal signal.

[0120] The abnormal cable refers to the charging cable that causes an abnormal charging during charging. The abnormal cable corresponding to the charging abnormal signal can be matched through a preset cable database, which stores different abnormal cables corresponding to different charging abnormal signals. The cable database is formed by those skilled in the art recording different abnormal cables corresponding to different charging abnormal signals in sequence, which will not be elaborated here.

[0121] Step 704: Process the abnormal cable based on a preset abnormal handling method.

[0122] The abnormal handling method refers to the method for handling the abnormal cable. The specific abnormal handling method will be described in detail in subsequent steps 800 to 805 and will not be elaborated here. Control a preset abnormal handling device to handle the abnormal cable with the abnormal handling method. The abnormal handling device refers to the device for handling the abnormal cable.

[0123] Refer to Figure 8 , the abnormal handling method includes the following steps: Step 800: Control the charging gun to stop charging, and after stopping charging, control the charging mobile device to move the charging gun to a preset photographing and detecting area to obtain the interface image information of the charging gun.

[0124] The photographing detection area refers to the area used to photograph the charging port of the charging gun. The photographing detection area is set in advance by those skilled in the art and will not be elaborated here. The interface image information refers to the image of the charging port of the charging gun. The interface image information is obtained by photographing with a camera on the photographing detection area.

[0125] Control the charging gun to stop charging, and after stopping charging, control the charging mobile device to move the charging gun to the photographing detection area, so as to control the camera in the photographing detection area to photograph the charging port of the charging gun, and obtain the interface image information of the charging gun.

[0126] Step 801: Determine whether the abnormal cable in the interface image information contains a preset abnormal feature.

[0127] The abnormal feature refers to the feature that causes the abnormal cable to be abnormal. The abnormal feature is set in advance by those skilled in the art and will not be elaborated here. By judging whether the abnormal cable in the interface image information contains an abnormal feature, it is known whether the reason for the abnormal power of the charging gun is on the surface of the charging gun, so as to know whether the abnormal feature can be directly processed.

[0128] Step 802: If the abnormal cable in the interface image information contains an abnormal feature, determine the abnormal type according to the interface image information and the abnormal feature. The abnormal type includes foreign object abnormality and oxidation abnormality.

[0129] The abnormal type refers to the classification of the abnormal situation that occurs during the charging process according to the characteristics presented by the abnormal cable in the interface image information. The foreign object abnormality refers to the foreign objects existing at the interface of the abnormal cable. For example, there is dust, debris, metal chips, etc. at the interface. The oxidation abnormality refers to the fact that the metal part of the cable interface surface reacts with oxygen due to being exposed to the air for a long time, forming an oxide layer.

[0130] By identifying the abnormal features in the interface image information, the abnormal type can be obtained. Image recognition technology is well-known common knowledge in the art and will not be elaborated here.

[0131] If the abnormal cable in the interface image information contains an abnormal feature, it means that the reason for the abnormal power of the charging gun is on the surface of the charging gun, and the abnormal type needs to be matched first for subsequent steps.

[0132] Step 803: Based on the foreign object abnormality, determine the foreign object position according to the interface image information, the abnormal feature and a preset reference object, and control a preset clamping device to clamp and remove the foreign object based on the foreign object position.

[0133] A reference object refers to an object used to assist in comparing the actual sizes and positions of various features in an image. The size and position of the reference object are both preset by those skilled in the art and will not be elaborated here. The foreign object position refers to the position where the foreign object is located on the cable. The clamping device refers to a device used to clamp and remove the foreign object at the foreign object position. By knowing the position and size of the reference object in the interface image information and then combining with the actual position and size of the reference object, the scale of the image can be known. Then, by identifying the position and size of the abnormal feature in the interface image information and combining with the scale of the image, the foreign object position can be obtained.

[0134] When the abnormal type is foreign object abnormality, it is necessary to first determine the foreign object position and then control the clamping device to clamp and remove the foreign object at the foreign object position.

[0135] Step 804: Based on the oxidation abnormality, determine the oxidation area according to the interface image information, the abnormal feature, and the preset reference object, and based on the oxidation area, control the preset grinding device to perform grinding and removal with a preset grinding force value.

[0136] The oxidation area refers to the area on the cable where oxidation occurs. By knowing the position and size of the reference object in the interface image information and then combining with the actual position and size of the reference object, the scale of the image can be known. Then, by identifying the position, size, and area of the abnormal feature in the interface image information and combining with the scale of the image, the oxidation area can be obtained. The grinding device refers to a device used to grind the oxidation area to remove the abnormal feature in the oxidation area. The grinding force value refers to the force value used to grind the oxidation area to remove the abnormal feature in the oxidation area. The grinding force value is preset by those skilled in the art and will not be elaborated here.

[0137] When the abnormal type is oxidation abnormality, it is necessary to first determine the oxidation area and then control the grinding device to grind and remove the abnormal feature in the oxidation area with the grinding force value.

[0138] Step 805: If the abnormal cable in the interface image information does not contain abnormal features, report a charging abnormality prompt.

[0139] If the abnormal cable in the interface image information does not contain abnormal features, it means that the cause of the abnormal power of the charging gun is inside the charging gun. It is necessary to report a charging abnormality prompt to prompt the staff to check on-site.
